Re: [Elecraft] KX3 Utility Linux version
Ok, here’s what was sent to me to get the 32 bit KX3UtilityLINUX_1_16_6_25.tgz installed on Linux Mint ‘Sylvia’ Cinnamon Desktop edition 18.3 64-bit. Now the KX3 Utility is running. tnx to all that responded. de George WD0AKZ dit – dit --- Try these suggestions to get 32-bit running. * Dependencies for use with Elecraft Linux-based Utilities 1) 32 bit vs 64 bit Distributions The Elecraft Utilities for Linux are 32-bit and require installing 32-bit compatiblity libraries on 64-bit distros that will allow 32-bit apps to run. On Unbuntu 14 and later based distros: sudo apt-get install libwebkitgtk-1.0.0:i386 sudo apt-get install libcanberra-gtk-module:i386 sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libglib2.0-0:i386 libsoup2.4-1:i386 libgtk2.0-0:i386 2) cURL must be installed on your Linux distro for FTP You will have to install cURL if it is not pre-installed. Most distros have it pre-installed, but not all. It is easy to install from a terminal: sudo apt-get install curl 3) Ensure your DialOut groups are set up properly Most users, other than root and members of the dialout group, do not have read/write permissions on the serial port device files. The Utilities cannot access the serial ports if the user does not have r/w permissions. An easy way to set the permissions is to add the user to the dialout group. sudo adduser username dialout 4) All files and directories included in the gzipped tar file must be kept together in the same location. The "Help directory", "Libs" directory (ie k3util Libs), and executable binary (ie k3util) must all be located together in the same directory. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Field Day rig experience
Will... A small nit... perhaps my ignorance... but, I think that the roofing filter [by whatever name] comes after the first mixer, at the so-called IF frequency. Your points are well made. I think the far out SDR's speak more to what can conceivably be done versus what's the design approach that best meets a broad range of desirable receiver parameters. Elecraft seems to have found the sweet spot in the battle of trade offs. ...robert On 6/12/2018 15:49, WILLIE BABER wrote: More then one so2r operator has noted that the 7300 will overload in an so2r situation so that you cannot clearly hear on 7300 when the other radio is transmitting (yes, on a different band).

Sherwood himself notes that using the SDR radio (i.e, without a superhet front-end) means reducing gain to limit ADC overload, but he has also suggested that blocking dynamic range is over-rated. Generally this is true, dynamic range is over-rated if you are using one radio. However, blocking isn't over-rated in a field day situation (more than one radio) or if you have a neighboring op running high power, or in legal-limit multi-op situations (with antennas relatively close to each other), or in legal-limit so2r.

While SDR radios have their advantages, some of the advantages of superhet radios still exist today, namely, that a so-called roofing filter front-end (which is just a mode-specific filter ahead of the first mixer) will deliver outstanding blocking AND as much sensitivity as required (compared to SDR).

[Elecraft] K3S USB Port
I thought I would share this with the group. With all the lightning that I have during the summer months. If find myself unplugging the USB cable several times (4 or 5 or more) a day to be cautious. I started thinking that any mechanical connector eventually will fail or have issues. So I found a USB-B male to USB-B Female 3' made by Startech. This way I leave the cable plugged into the radio and make my disconnect at the cable end. The cables are 6 bucks and I would rather wear one of them out than the USB on the K3. I have not seen any RF issues with these cables, but I add some ferrite to end.

Re: [Elecraft] Mobile Grounding for KX3 and KXPA100
The exception (There are always exceptions!) to what Bob writes below is the type of vertical which requires a counterpoise, but not radials such as quarter-wave. This would include verticals like the Cushcraft R8. These do require a ground for static discharge protection. But, as Jim, K9Y, has pointed out numerous times, this ground is NOT for the antenna's operation/radiation. Buy Ward Silver's, N0AX, book on Bonding and Grounding, if you can find it. Jim's web site is free! Don's advice on lightning is paramount for safety! If lightning is within 10 miles, disconnect all antenna cables, and enjoy your food, beer, reading material, etc. We had two Airmen killed at Canon AFB NM when this requirement was ignored. Disconnecting antennas during last year's FD for five hours dropped us out of the Top 20 in 1A by one! However, unlike two years previous, we suffered not equipment damage and, most importantly, no operator damage. Sadly, the Cibola National Forest just announced it will close down (about 95%) this Friday due to extreme fire danger. I am seeking an alternative that meets our criteria. An EOC sounds enticing.

On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used. Dynamic range of all of these radios is quantified in the receiver performance table at www.sherweng.com, specifically the fifth column (“100 kHz Blocking”).

Re: [Elecraft] Mobile Grounding for KX3 and KXPA100
On 6/11/2018 2:09 PM, Smedes, Tad - Comcast wrote: I am planning to use my KX3 and KXPA100 powered by Budipole PowerMini and LiFEPO4 battery for field day this year and have a question about grounding. When I am using them both at the home station they are grounded to each other and every other piece of equipment in the shack using a ground bar and copper straps. Let's use the right words for the right things we do. BONDING is what we are doing when we may an electrically short and mechanically robust connection between equipment and between all of the grounds in our home. GROUNDING is a connection to Mother Earth. It's purpose is Lightning Protection. When I use my KX3 by itself mobile I have never grounded it and never had an issue. In general, radio equipment should be bonded together, but should NOT be bonded to the vehicle. You MUST run a pair of big wires direct from the battery to the rig. NEVER use the vehicle chassis as a path for return DC current -- that's a recipe for disaster! The only connection to the vehicle should usually be the coax shield to the best metal you can find at the antenna, because the metal in the car body acts as the counterpoise for your antenna. In other words, it is PART OF the antenna! Make sure that whatever metal you bond to actually goes to the rest of the car's chassis. That's often not easy -- even when there are metal to metal mechanical connections, they're often insulated from each other by paint! Is there anything special that I need to do do when I hook the KX3 to the KXPA100 while mobile, and what is it? and or what do the rest of you do when running mobile with a KX3 and KXPA100 for grounding? 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
